Via ABC News, which was given a partial transcript, Gingrich listed his accomplishments this way:

“I helped Ronald Reagan and Jack Kemp develop supply side economics. I helped lead the effort to defeat communism in the Congress.”

He also made clear he's stunned by his own success now:

“Whereas I would have thought originally it was going to be Mitt and not-Mitt, I think it’s going to — it may turn out to be Newt and not-Newt,” Gingrich tells Hannity, according to excerpts of the interview. “And that’s a very different formula than, frankly — I mean we’re having to redesign our campaign strategy because we’re at least 60 days ahead of where I thought we’d be.”

The country, he argued, is "talking to itself" and there's only one cure: More Newt.
